In another cmd terminal write >>cd Program Files\SSH Communications Security\SSH Secure Shell >>ssh2 -p 7777 localhost >>gnome-terminal & - Linux ssh -l myuserid -L 7777:work:22 gate cat - ssh -p 7777 localhost sftp -oPort=7777 localhost OR ssh -f -l username -L 7777:remotehostname:22 gatehostname -N ssh -p 7777 localhost An alternative to ssh tunnel is to use vpn. For INST-NAME you have to login as root to your computer and create a new configuration file at /etc/vpnc. nano rutgers-vpn.conf IPSec gateway vpn.rutgers.edu IPSec ID rutgers-ipsec IPSec secret rutgers Xauth username myusernamehere After this you just have to do: sudo vpnc rutgers-vpnc # To start vpnc sudo vpnc-disconnect # To logoff from vpnc Yet another use of ssh is that it can open a socks port to tunnel through, say, instead of using vpn. ssh -D 3847 username@remotehost.someuni.edu After connecting you have to check your connection preferences and tell either your ethernet of wireless card that you want to use the socks port via 3847 through
